It was on this day in 1965 that thousands of marchers, led by Dr. Martin Luther King Jr., left Selma, Alabama, headed to Montgomery, to protest the disenfranchisement of African-American voters. They had attempted the march twice before, earlier in the month, but the first time they had been badly beaten by state troopers and deputies, and the second time they were ordered to turn back. This time, under court order, they were allowed to proceed, and by the time they reached the state capitol in Montgomery, there were 25,000 marchers, many answering King’s call for people across the country to come and join. One of the people marching at the front of the line, arm in arm with Dr. King, was Rabbi Abraham Joshua Heschel, King’s friend and colleague. Heschel said: “For many of us, the march from Selma to Montgomery was about protest and prayer. Legs are not lips and walking is not kneeling. And yet our legs uttered songs. Even without words, our march was worship. I felt my legs were praying.”
